Problems solved by technology

[0004] 1. The energy supply system depends on a variety of energy sources. Except for electric energy, these energy sources are relatively restricted by regional conditions, resulting in many restrictions on the establishment of energy stations. This not only makes the construction cost of energy stations very high, but also limits the energy station. Promote application
[0005] 2. Since the energy station requires a large footprint, the construction cost is high
[0006] 3. Due to the dependence on a variety of energy sources, especially the pressure on the use of electric energy, and the poor switching stability between various energy supply modes, it affects the use effect

Description

technical field [0001] The invention relates to the field of energy stations, in particular to a regional energy station that can be jointly built with a substation. Background technique [0002] A substation refers to a place in the power system that transforms voltage and current, receives electric energy and distributes electric energy. Its location is determined according to a certain power supply radius principle, and the capacity is allocated according to the load demand of buildings in the supply area. Among them, the cooling power load Accounting for 25-60%, it is used to meet the needs of traditional decentralized and independent cooling and heating systems. [0003] The energy station is mainly to realize the energy supply for users in a certain surrounding area, and to provide unified cooling, heating and hot water supply to the buildings. The existing energy station adopts an intensive energy supply system, which is a decentralized, An independent cooling and he...
